“…The critical stress c  for brittle materials has been successfully shown in the literature to be equal to the tensile strength of material (Ayatollahi & Torabi, 2010a, 2010bTorabi, 2013d;Torabi et al, , 2014dTorabi & Amininejad, 2015aTorabi & Pirhadi 2015;Torabi & Abedinasab, 2015a.

“…Moreover, because EMC acts as a bridge between the linear elastic and elastic-plastic analyses, it is expected that it can basically be linked to various brittle fracture criteria, e.g. the maximum tangential stress (MTS) and mean stress (MS) (Ayatollahi & Torabi, 2010a, 2010bTorabi, 2013d;Ayatollahi et al, 2011aAyatollahi et al, , 2011bAliha & Ayatollahi 2013;Mirsayar et al 2014;Torabi et al, , 2014dTorabi & Amininejad, 2015aTorabi & Pirhadi 2015;Torabi & Abedinasab, 2015a criteria, the averaged strain energy density (ASED) criterion (Lazzarin & Zambardi, 2001;Berto & Lazzarin, 2014;Torabi et al, , 2015cBerto & Barati, 2011;Gomez et al, 2007Gomez et al, , 2009aGomez et al, , 2009bBerto et al, 2007Berto et al, , 2012Berto & Ayatollahi, 2011;Berto & Lazzarin, 2009;Aliha et al 2016), the cohesive zone model (CZM) (Gomez et al, 2000(Gomez et al, , 2006Gomez & Elices, 2003;Cendon 42 et al, 2015) and the finite fracture mechanics (FFM) (Sapora et al, 2013(Sapora et al, , 2015Cornetti et al, 2012Cornetti et al, , 2014Weißgraeber & Becker, 2013;Carpinteri et al, 2008) etc. under different in-plane loading conditions.…”

“…При моделировании разрушения в пре-делах материальной поверхности меры ноль используются когезионные элементы [16][17][18][19] конечно-элементного пакета [20] или контактные элементы системы [21]. В работах [22][23][24] рассмотрен широко используемый билинейный закон распределения взаимодействия в когезионной зоне от раскрытия трещины с ниспадающим участком. Основным недос-татком данного подхода является то, что когезионные элементы должны располагаться на траектории разрушения, которая зависит от новых материальных поверхностей.…”

“…Brittle fracture criteria published under mixed mode loading conditions are both stress based and energy based. As a well-known stress-based criterion, the maximum tangential stress (MTS) criterion can be named (see, e.g., the V-MTS criterion [38][39][40][41] and the U-MTS criterion [42][43][44]). The concept of the MTS criterion is, in fact, the same with that of the point method in the theory of critical distances (TCD).…”

“…The MTS criterion has been verified several times in the past by means of extensive experimental results achieved from the fracture tests on the notched specimens made of various brittle materials, such as PMMA [38,41,42], polycrystalline graphite [39,43,44], and soda-lime glass [40]. Concerning energy-based fracture criteria, the strain energy density (SED) criterion is the most popular and powerful tool for analyzing mixed mode I/II brittle fracture in notched domains (see for instance Refs.…”
